20 points! answer if you are going to actually ! also if the images don't load, give it a !

so basically i need to know if the polygons are similar and the justification of it. if you could answer at least three that would be great

need more details click on the more detail button to ask me (many people put their answer as "i'm confused", its really annoying)

For the two right triangles, they are not similar because the ratio from side to its corresponding side is not the same. (6:7 and 4:5)
For the other triangles, they are similar because the ratio from a side to its corresponding side is the same. (2:3)
The rectangles are not the same because the ratio from one side to its corresponding side is not the same with all of them. (1:2 and 7:10)
The squares, yes, because they're both squares.
